N.A. Astrov's design team at Moscow Factory No. 37 was assigned the task of designing amphibious and non-amphibious scout tanks in 1938. They produced the T-30A and T-30B prototypes. The former was to be manufactured as the T-40 amphibious tank starting in 1940. It also led to the T-40S (sukhoputniy, 'dry-land' version), a heavier tank prototype which was considered too complex to manufacture. The T-30B prototype, sharing the T-40's chassis but simpler in construction and with heavier armour, was accepted as the T-60 scout tank, and began production in July 1941, just after the German invasion.

Although at first intended to carry a 12.7 mm machine gun like the T-40 the armament was later upgraded to the 20 mm TNSh cannon, a tank version of the ShVAK, on the advisement of the Chairman of the Council of Ministers, V.A. Malyshev. This weapon had the same armour-piercing capability as the German 37 mm due to its high muzzle velocity (15 mm of perpendicular armour at 500 m range).

The T-60 was also used in the design of the experimental T-90 antiaircraft tank. This project switched to the T-70 light tank, and was finally cancelled without any production.
